Working Mac build

I've finally managed to construct a Mac OS X package that works on machines that aren't mine: robolock-II-0.1.dmg

This is identical code to our final entries. Only the packaging has changed.

For the curious (especially me-in-the-future), I ended up with the following process after much trial and error:

  1. Install a 32-bit (not 64-bit) Python from -- I used this one.
  2. Install a suitable pre-built pygame package from -- I used this one.
  3. Create a virtualenv using the aforementioned Python and pass --system-site-packages so that the aforementioned pygame is available.
  4. Install game depencies in this virtualenv, install py2app, run python py2app or whatever.
